Ryan Braun's run-scoring single in the fifth inning proved to be the difference for the Brewers, who bounced back from a 4-3 loss on Wednesday. George Kottaras, Jerry Hairston Jr. and Yuniesky Betancourt each added an RBI.
Wolf (1-1) gave up two runs -- both off solo homers -- on six hits to pick up his first career postseason win. The left-hander struck out six and walked one.
With the victory, the Brewers secured at least one more home playoff game. Milwaukee excelled at home during the regular season, setting a franchise record by going 57-24, and the club has went 4-1 at Miller Park during the postseason.
Kyle Lohse (0-2) allowed three runs on six hits over 4 1/3 innings to take the loss.
